LAB SCHEDULING The laboratory will operate on a semi-open lab policy. That is - lab
work is possible at times other than and including the officially scheduled lab period. As
you all have had 2+ years of training in Chemistry, it is expected that you can work
safely with a minimum of supervision.

Mondays 3 pm - 5 pm

Laboratory will be open for inspection of equipment and instruments. Use this time to
plan your procedure and be sure you understand the instrument operating instructions.
There will be NO experimentation during this period.

Wednesdays 1 pm - 5 pm

Regular Lab Period.

You will be challenged to complete the experiments within a single lab period. Please
be prepared to make liberal use of the additional lab time.

Laboratories will be performed on a rotating schedule with the class divided into three
groups. Three experiments will run concurrently each week.

It is unavoidable that the lecture and laboratory will not move at the same pace, nor
cover subjects in the same order. It is therefore imperative that you act as a student and
learn as much as you can about each experiment through reading BEFORE you come to the lab.
Be sure to read the appropriate chapters in the lecture text and the lab description
before performing an experiment an experiment.
